Recommend CAD Parameters for Better Milling
, by Kevin Park
It is important to choose the right milling material at the beginning.
It will affect to all parameters after that.
Cement gap: 0.06-0.04mm
(You need more cement gap between crown and custom abutment for 'One-step milling'.)
Horizontal margin thickness (zirconia): 0.25mm
Horizontal margin thickness (glass ceramic): 0.4mm
Margin Angle 60 degree
Vertical: 0mm
Below margin: 0mm
Milling bur diameter: 0.8mm
